MIC2877-4.75YFT-TR by Microchip Technology
2MHz 6.5A Isw Synchronous Boost Regulator
| Status: | Active |
|---|---|
| Series: | MIC2877 |
| RoHS: | Compliant |
The MIC2877 is a compact and highly efficient 2MHz synchronous boost regulator with a 6.5A (typical) switch. It features a bidirectional true load disconnect function that prevents any leakage current between the input and output when the device is disabled (EN = GND), protecting the input supply and improves the start-up performance.
The MIC2877 has the input voltage range between 2.5V and 5.5V and provides a 2A output continuous current for VIN = 3V and VOUT = 5V. Fixed output and adjustable output versions are available.
The MIC2877 operates in Bypass Mode automatically when the input voltage is higher or equal to the target output voltage. At light loads, the boost converter goes to Pulse Frequency Modulation (PFM) mode to improve the efficiency. In shutdown mode, the regulator typically consumes less than 2µA.
The MIC2877 also features an integrated anti-ringing switch to minimize EMI, overvoltage and overcurrent protection, UVLO and thermal shutdown. The MIC2877 is available in an 8-pin FTQFN 2mm x 2mm package.
